Ignore the ENODEV failures returned by kernel_sendmsg(). These errors
mean either the local port has closed or the remote has gone down.
Neither of these scenarios are fatal and will eventually be handled
through packets that are later queued on the control port.
Also improve the logging messages to print the error code returned by
kernel_sendmsg().

Increase the socket recvbuf for the ns so control packets are not
dropped in heavy traffic situations. This change will not
actually set the recvbuf to INT_MAX but to the system defined rmem_max
for sockets.

Move sys heap allocation code into the system_qcom_sg_buffer_alloc()
function to allow core allocation code to be used from other modules.
Additionally, move the allocation of the struct qcom_sg_buffer
out of system_qcom_sg_buffer_alloc(), so that other modules can
allocate their own buffer structs with qcom_sg_buffer as an embedded
member.
Each other module will then have dmabuf->priv pointing to the
qcom_sg_buffer member of their custom buffer struct. This is needed
to allow the qcom_sg_ops.c functions to continue working as is.

When a del client message is received from remote, the corresponding
server port is deleted. And then, a del server message is announced
for this server. As part of handling this message, ns will try to
delete this server port again and returns a -ENOENT error. Return
value from server_del is returned back to qrtr_ns_worker and any
non-zero value is printed to the serial port. This is flooding the
serial port display. Returinng 0 in this case as this is not an error.
